genetic water retention problems - need a good bodybuilding diuretic

I'd like some feedback about what diuretic could i take this summer during my cut in order to maximize results. I'd like something that is effective at removing water retention and that i can use on a longer term (everyday for like 4 weeks).

any tips? (something i can buy on bodybuilding.com)

L2 by Cellucor worked great for some of my buddies. However, I've personally never tried it.

Green tea, water with freshly squeezed lemon, and distilled water are all natural diuretics that can help during a cut.
